Hi,
Prices will always increase over time with any supplier you choose. Sure we have had a price increase, but so have BT, Sky & Virgin, so basing your decision on this is not the way forward.
look at the services on offer, look at what services you actually need or use. Look at the pro's & cons for all providers before you decide.
For example, with our TV boosts, these are a one month commitment. so if you take Sky Movies, and you find you hardly watch it, you can then remove this at the end of the month. Some provider may require you to keep this for 12 months etc, so look at these aspects before you make a decision.
One thing to keep in mind however is that you will get excellent customer support via these forums 
Thanks
Karl.
